Micro Second Bus Interface (MSC0)
The MSC interface provides a serial communication link typically used to connect power
switches or other peripheral devices. The serial communication link includes a fast
synchronous downstream channel and a slow asynchronous upstream channel.
Figure 3-6 shows a global view of the MSC interface signals.

Figure 3-6 Block Diagram of the MSC Interface
The downstream and upstream channels of the MSC module communicate with the
external world via nine I/O lines. Eight output lines are required for the serial
communication of the downstream channel (clock, data, and enable signals). One out of
eight input lines SDI[7:0] is used as serial data input signal for the upstream channel. The
source of the serial data to be transmitted by the downstream channel can be MSC
register contents or data that is provided at the ALTINL/ALTINH input lines. These input
lines are typically connected to other on-chip peripheral units (for example with a timer
unit like the GPTA). An emergency stop input signal makes it possible to set bits of the
serial data stream to dedicated values in emergency cases.
